Interstellar's ending analysis.

In Interstellar, why did the daughter tell her father to leave? To keep her father alive.

In interstellar space, the earth was completely destroyed by famine and sandstorm, which forced the underground NASA to consider the future of mankind: we must emigrate to other planets.

They intend to use wormholes to travel to distant galaxies to find new livable planets, and put forward two complicated plans: one is to transport the earth's population to this new world; B plans to abandon those populations on the earth and use prefabricated embryos to breed new humans on new planets.

Finally, because the first two planets are obviously uninhabitable and the third planet is almost impossible to reach, Cooper and Brand come up with a crazy plan. Fly around the black hole and use gravity slingshot effect to eject their spaceship forever.

This is the basic plot of the film, but the ending is far more than that. Before discussing the intention of this film, let's take a look at Interstellar's last twenty minutes.
